When you first apply power to the LPCXpresso through the USB cable, you get a "New Hardware" message? If so, it sounds like the LPCXpresso DFU device is not installed, there was a problem with the install, or the board is just broken. The DFU operation has to work reliably to do anything. Plug the board back in, and when you get the "New Hardware" message, point it at the "<install>\Drivers\DFU\MassDfu.inf" to install the DFU support. Then try to transfer a software probe onto the board (see below).

Hello,
Thanks for the quick response.
With the Device Manager open, as soon as i plug in the LPCXpresso board, i get a yellow exclamation mark in the Device Manager's Universal Serial Bus Controllers section indicating a unnamed USB Device with the error "This device is not configured correctly. (Code 1)".
Of course, i cannot install the driver since that was presumably already done when the LPCXpresso tools were themselves installed.
Are there any switches in the S/W which need to be activated after installation to allow it to recognize the USB port?
I have contacted the supplier (Future Electronics) to see if they can bring over some other boards for me to try.
Hopefully, that will fix the problem. It is odd, however, that the LPC1114 seems to be running OK (since it flashes the LED from the code programmed at the factory). Of course, it could simply be the LPC3154 which controls the USB port interface which is not working properly.
Thanks again, J
